In a sale, the original price of a bag was reduced by 1/5. The sale price of the bag is £29.40. Work out the original price.
£29.40 represents 4/5 of xThus to find x, we must multiply 29.40 by 5/4:
29.40/4 = 7.35 (this is 1/5) 7.35 x 5 = 36.75 (this is 5/5, the original price)
Original price = £36.75
